An automatic data logger system for monitoring tensiometers, piezometers, and auxiliary equipment is described. The results from the installation examples in Malaysia illustrate that significant changes in the soil water conditions on unprotected
Genesis of an endoreic piezometric coastal depression in sub-Sahelian Western Africa : the Continental Terminal Aquifer of Trarza (Mauritania)
The Trarza Aquifer is the main resource of drinkable water for Nouakchott. After reviewing the main mathematical models for piezometric depression, this study attempts a conceptualization of the piezometric evolution of this phreatic aquifer
According to 60years long piezometric data, in the chalky aquifer of northern France, one can shows that extreme events are not recent facts in spite of the drought of 1976. Statistical distribution of levels for each month is used to draw a simple
network on which it is possible to compare one year with the others. For predicting stochastically piezometric levels, piezometric differences between a given month to its following have been studied. It appears that variations are erratic during winter

Measurements from an instrumental network in a small area have been used to establish index-based models for topographic and climate-related controls of piezometric response. The example, in this study, uses the topography index of TOPMODEL, in GIS
Relationships between soil color patterns and depth and duration of water tables were studied using piezometers in three soil hydrosequences that had developed from different colored parent materials. Insufficient low chroma colors was the primary
Pour 5 des 6 piézomètres de référence, la cote la plus élevée des 30 dernières années s'est produite en 1983 (mai ou juin), conséquence des pluies importantes de cette année. Les périodes de retour se situent généralement entre 25 et 40 ans.

Dans un bassin-versant de forêt tropicale des piézomètres de faible profondeur répondent instantanément aux chutes de pluie. Afin de comprendre le mécanisme de pénétration de l'eau dans le sol, on injecte de l'eau au tritium sous la surface qui
The intermediate-field hydrological response to the 6th April 2009 L’Aquila earthquake has been studied using groundwater level data that were recorded by 6 piezometers in the Acque Albule Basin (Tivoli travertine quarry area) and in the Cornicolani
at 5 piezometers located in the travertine quarry area began to decrease, while the water level slightly increased in the Pozzo del Merro karst lake that is located in the carbonate aquifer. To explain these variations, a possible conceptual model
